The medical industry utilizes ultrasonically welded parts for a variety of applications. These parts include face masks, blood and gas filters, arterial filters, and anesthesia filters, which are all made from dissimilar materials such as medical-grade ABS or polyethylene. Ultrasonic welding is the preferred technique for assembling these components due to its compatibility with the materials used.

The automobile manufacturing industry heavily depends on welding technology to join plastics for creating components such as door panels, instrument panels, and steering wheels. This process has low capital costs and is automated with reduced cycle times, providing flexibility in production.

Ultrasonic welding technology is commonly used in the electronics industry to join wires, which simplifies the creation of small circuits and makes the process more accurate and efficient. Additionally, this process is also utilized for assembling electric motors, capacitors, and storage media devices.
